T 0 all whom it may concern:

Be it known that I, Jonx Y. ALLIsov. a citizen of the United States. residing in the city, county, and State of New York, have invented a new and useful Window-Cleaning Device, of which the following is a specification.

My invention consists of a device for cleaning the outside of a window from within the )lace of location of the window, the same embodying a brush or wiper, means for presenting the latter to the glass, while bemg held in contact therewith, and means for operating the bruslr from the opposite side of the glass.

For the purpose of explaining my invention, the accom anying drawing illustrates a satisfactory 10(U0i)i0l1 of the same to )ractice, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific arran ement and organization shown and described.

Figure 1 represents a perspective view of a form of a window cleaning device embodying the invention. Fig. 2 represents a vertical section thereof. Fig. 3 represents a. side elevation of a portion of modified form.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawing:.-\ designates a window, which is composed of a pane of glass B and the frame C, to which the same is attached in usual manner. In the present case said window is that of an automobile or other vehicle, the glass being liable to be splashed or coated in front or outside with dirt, dust, etc, access to which is inconvenient from within the vehicle.

In carrying out my invention, I employ a brush, which is located in front of the glass, and composed of a strip D of soft rubber or otl er suitable material and the gravitating head E, whose upper end carries said strip and which has connected with its sides the gudgcons or axes F, whose bearings are on the blocks G, the sides of which are grooved and adapted to slide in vertical direction on the guide rods H, whose ends are connected with brackets J, K res )ectively on the upper and lower portions of the frame C.

L designates straps, of tape or other pliable material, whose upper ends are adapted to be wound on and unwound from the pulle 's M on the spring roller X of the order of a shade fixture, the'bcarings P of said pulleys being on the upper brackets J, said straps being continued downwardly and connected with the pins Q on the sides of the head E above the axes F of the lattel',thc straps also extending downwardly from said pins to the bottom of the frame 0 after which they pass through the openings R in the side of the frame to the rear of the frame, where they are joined by the operating knob or button S, whereby both straps L may be simultaneously drawn or operated from the reaixof the window.

In Fig. 3, I show a cord '1 in lieu of a piece of tape, said cord being connected with the side of the head E, as at Q, and producing the same results as said piece of ta )e.

The operation is as follows: Vhen the front of the glass is soiled from any cause, it may be cleansed from the back thereof, which is within the vehicle. For this purpose, the straps L are drawn rearward by the button or knob S, whereby the brush is lowercd and owing to the connect-ion of, the straps with the head E, the connection being eccentric, the upper limb or portion of the head E is turned 011 its axis inwardly towards the glass, carrying wit-h it the strip D and pressing it lirmly against said glass, see Fig. 1. As said strip is lowered by the straps, it remains in contact with the glass and acts as a wiper to brush and cleanse the same, it being evident that the straps are unwound from the pullcvs M, as the brush descends. When the knob S is let-go, the spring roller X rotates in reverse order and so rewinds the straps on the pulleys and raises the brush, the head E owing to its gravitating nature returning to its normal )osition and removing the strip D from the glass, see Fig. 2, after which the operations may be repeated.

In some cases, it may be desirable to set the spr ng roller further from the frame C. In this case, the brackets J, K are each formed of separate parts for connecting them, and furthermore provided with a series of openings to adapt the guide rods II to be placed in adj ustmcnt relatively to the po sition of said roller.

Having thus described my invention, what I claim as new and desire to secure by Letteis Patent, is

1. In a window cleaner, a spring roller :1 support for the bearings thereof, a gravitating head having lateral axes, a wiper on said head, rollers on said axes, guides for I said spring roller, said guide-rods being adsaid rollers, and pliable means passed over the spring roller and having one end connected with the ends of said head above said axes and the other ends passed downwardly therefrom.

'2. In a window cleaner, a spring roller, a gravitating head having lateral axes, rollers on said axes, guides for said rollers, pliable means passed over the spring roller and having one end connected with the ends of said head above said axes and the other ends passed downwardly, and brackets for supporting the bearings of said spring roller.

,3. In a window cleaner, a spring roller, a gravitating head having lateral axes, rolleps on said axes, guides for said rolleis, pliable means passed over the spring roller and having one end connected with the ends of said head above said axes and the other ends passed downwardly therefrom, and adjust able brackets for supporting the bearings of justably mounted.

4. In a window cleaner, the combination with the frame and brackets secured near the upper end thereof, and brackets on the frame near the lower end thereof, of vertical gulde rods mounted in said upper and lower braek ets, a spring roller having its bearings mounted in the upper brackets ahead having lateral axes at its ends, said head being enlarged below its axes, whereby it automatically assumes a vertical position, rollers on said axes guided on said rods, lateral pins on said head above said axes, and pliable members. passed over pulleys on said spring roller with one end of each connected to said )ins and the other ends extended downwardfy therefrom.
